XML python'dan veri al

Question

Yaklaşık 6 alan almak için Google XML'den geçmeye çalışıyorum. Google Apps Alanındaki kullanıcı profilleri için XML feed'ini çekmek için Google tarafından sağlanan gdata'yı kullanıyorum. Bu sonuç ise:

import atom 
import gdata.auth 
import gdata.contacts 
import gdata.contacts.client 
from lxml import etree 
from lxml import objectify 

email = 'admin@domain.com' 
password = 'password' 
domain = 'domain.com' 

gd_client = gdata.contacts.client.ContactsClient(domain=domain) 
gd_client.ClientLogin(email, password, 'profileFeedAPI') 

profiles_feed = gd_client.GetProfilesFeed('https://www.google.com/m8/feeds/profiles/domain/domain.com/full?max-results=300') 

def PrintFeed(feed): 
    for i, entry in enumerate(feed.entry): 
    print '\n%s %s' % (i+1, entry.title.text) 

print(profiles_feed) 
PrintFeed(profiles_feed) 

profiles_feed2=(str(profiles_feed)) 

root = objectify.fromstring(profiles_feed2) 

print root 

print root.tag 
print root.text 

for e in root.entry(): 
    print e.tag 
    print e.text 

Bunu iade etmek alabilirsiniz:

Verileri ayrıştırmak için LXML kullanmaya çalışıyorum, ancak bu kadar iyi yürümüyor, bu benim kodudur besle ve sonra giriş, ama daha uzak keşfedemiyorum. İhtiyacım olan şey, ns1 adındaki ad alanlarını ve ns1 organizasyonundaki org alanını oluşturur. Biraz kayboldum, bu yüzden herhangi bir yardım büyük beğeni topluyor.

Answer 1

Hep kolaylığı nedeniyle, öğrenmeye API BeautifulSoup kullanmak tavsiye:

from BeautifulSoup import BeautifulStoneSoup as Soup 

soup = Soup(open(filename)) 
for tag in soup.findAll('ns1:name'): 
    print tag.find('ns1:familyname').text 
    print tag.find('ns1:fullname').text 
    print tag.find('ns1:givenname').text 
for tag in soup.findAll('ns1:organization'): 
    print tag.find('ns1:orgtitle').text 
    print tag.find('ns1:orgdepartment').text 
    print tag.find('ns1:orgname').text 

Örnek çıktı:

Person 
Name Person 
Name 
JobField 
DepartmentField 
CompanyField 

Answer 2

Mutlaka çalışmanızı kolaylaştıracak lxml.It ile Xpath Expressions kullanmayı deneyebilirsiniz .

Örneğin xml file: Firefox'un firebug eklenti kullanmak xpath için aşağıdaki kodu

>>> import lxml 
>>> from lxml import etree 
>>> et = etree.parse("test.xml") 
>>> value = et.xpath("/document/name/*/text()") 
>>> value 
['Person', 'Name Person', 'Name'] 

Daha

<document> 
     <name> 
       <familyName>Person</familyName> 
       <fullName>Name Person</fullName> 
       <givenName>Name</givenName> 
     </name> 
</document> 

.
